For testing power consumption, we took our test system and plugged it
into a Kill-A-Watt power meter. For idle numbers, we allowed the system
to idle on the desktop for 15 minutes and took the reading. For load
numbers we measured the peak wattage used by the system while running
the OpenGL benchmark FurMark 1.10.1 at 1024×768 resolution. We also ran four game titles at 1920×1080 and averaged the peak results recorded the highest Wattage seen on the meter for the gaming results.
Power Consumption Results: When it comes to power consumption we found that all three of the NVIDIA GeForce GTX 650 Ti based cards were shockingly similar to one another despite the difference in core clocks and PCB design. With the system at idle all averaged just a few Watts under 100 and at full load all average right around 240 Watts. These are solid power numbers and make sense as the NVIDIA GeForce GTX 650 Ti had a TDP of 110 Watts and requires at least a 400W power supply for proper operation.
